Storage Performance in CloudStack

Agenda:

6:30pm - 7:30pm: Storage Performance in CloudStack by Mike Tutkowski, Senior CloudStack Developer, SolidFire

The idea is that cloud-service providers only tend to host about 10% of an enterprise's compute workload these days because enterprises are not confident enough to place their most mission-critical apps in the cloud due to performance variability. One day the storage resources in the cloud may not be heavily utilized and your app's performance is great while the next day your app's performance is terrible because there is much more activity in the cloud.

What I've been working on is integrating SolidFire's Quality of Service (QoS) capabilities. These provide cloud-service providers with the ability to guarantee IOPS to apps on a volume-by-volume basis.

In general I start the presentation discussing how CloudStack was designed from the ground up to deal with preallocated storage, then move into the plug-in architecture that was added in 4.2 and how I leverage this to deliver QoS.
